[AMD GPU] Water Shader turns into a pixelated mess

Hello,

I ran into a problem with water shader, the screen is a pixelated mess when you are close to the water (I tried Low, Medium and High texture quality). https://i.imgur.com/gEmyoLy.jpg and https://i.imgur.com/hGGX5zY.jpg

Here is a video (not mine) that shows the issue better than images https://www.twitch.tv/konquesting/clip/ImportantClumsyPanHoneyBadger

It's a fresh Morrowind install with only the following mods:

• Correct UV Rrocks at Morrowind
• Correct Meshes at Morrowind
• Morrowind Enhanced Textures at Morrowind

I have an AMD RX 580 GPU with Phenom II X4 and I've tested several version :

• openwm 0.46 nightly, Window 7 x64 with lastest WHQL driver 20.2.2
• openwm 0.45, Windows 10 x64 with lastest WHQL driver 20.2.2

There is already a post on openmw forum for this issue I've found nothing on gitlab https://www.twitch.tv/konquesting/clip/ImportantClumsyPanHoneyBadger

From what I read it's a GPU issue that were here already on openmw 0.44
